Abstract:
Vesicular stomatitis (VS) is an infectious viral disease that affects bovines, equines, swine, wild animals and humans. As it is indistinguishable from other vesicular diseases, mainly Foot and Mouth Disease (FMD), it causes restrictions in commercial livestock trade at national and international levels and also significant economic losses. As the epidemiology and maintenance of VS virus in nature are not clearly understood it is difficult to take effective control measures. VS was diagnosed in some regions of Brazil, such as Minas Gerais, Santa Catarina, São Paulo and Alagoas. Cattle and horses with clinical symptoms of drooling, shedding of the lingual epithelium, presence of vesicles on the oral mucosa were observed and reported to the National Animal Health Office health of Maranhão State, Brazil. Samples of serum of these animals were collected and sent to Laboratório Nacional de Agropecuaria for ELISA and virus neutralization and differential diagnosis for Foot and Mouth Disease (FMD). The results of ELISA confirmed the VS. In the differential diagnosis, the results were negative for FMD. Samples of bovine epithelial tissue for VS by PCR confirmation of diagnosis were collected and sent to Biological Institute of São Paulo. Molecular results confirmed the Vesiculovirus Indiana III (Alagoas/VSAV) infection.
